language and speech development
2014-09-17 04:17:09

Chuck Bednar for redOrbit.com - Your Universe Online Two separate, recently published studies are shedding new light on how humans developed the ability to produce and understand speech, and what factors contribute to the development of language during infancy. In the first study, researchers from MIT and several European universities report that the human version of a gene known as Foxp2 makes it easier to transform new experiences into routine procedures, and that engineering mice to...

Fruit Flies Take Time To Think Before Making Difficult Decisions
2014-05-23 06:58:38

Lawrence LeBlond for redOrbit.com - Your Universe Online It is common knowledge that most humans think before they act. A new study, published in the journal Science, makes the case that this cognitive ability can also be found in the fruit fly, and it seems these tiny insects take longer to make more difficult decisions, just like humans do. In the study, researchers from the University of Oxford's Centre for Circuits and Behaviour asked fruit flies to distinguish between ever closer...

Gene found in human speech problems affects singing, not learning in songbirds A genetic defect that profoundly affects speech in humans also disrupts the ability of songbirds to sing effective courtship tunes. This defect in a gene called FoxP2 renders the brain circuitry insensitive to feel-good chemicals that serve as a reward for speaking the correct syllable or hitting the right note, a recent study shows. The research, which was conducted in adult zebrafinches, gives insight into...

Selection in European populations of genes regulated by FOXP2, a key factor in development and language Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project. The method identifies gene sets that show evidence for positive selection in comparison with matched controls, and thus highlights genes for further functional...

Women More Talkative Than Men Because Thier Brain Is Designed That Way
2013-02-22 12:17:19

Michael Harper for redOrbit.com — Your Universe Online We´ve all heard the oft-repeated statistics about women talking more than men. And to back up those statistics, one previous study has shown that a part of the brain responsible for processing communication is simply larger in a woman than a man. Now, a new study adds to those claims by moving a step further, showing that the female brain is actually designed with communication in mind. Performed by doctors at the...

Findings could lead to greater understanding of sex differences in language acquisition Male rat pups have more of a specific brain protein associated with language development than females, according to a study published February 20 in The Journal of Neuroscience. The study also found sex differences in the brain protein in a small group of children. The findings may shed light on sex differences in communication in animals and language acquisition in people. Sex differences in early...

Learning How Song Birds Sing By Doing The Math
2012-12-21 14:32:30

Emory University Scientists studying how songbirds stay on key have developed a statistical explanation for why some things are harder for the brain to learn than others. “We´ve built the first mathematical model that uses a bird´s previous sensorimotor experience to predict its ability to learn,” says Emory biologist Samuel Sober. “We hope it will help us understand the math of learning in other species, including humans.” Sober conducted the...

Little Language Learners Have Head Start

Babies' ability to detect complex rules in language outshines that of adults New research examining auditory mechanisms of language learning in babies has revealed that infants as young as three months of age are able to automatically detect and learn complex dependencies between syllables in spoken language. By contrast, adults only recognized the same dependencies when asked to actively search for them. The study by scientists at the Max Planck Institute for Human Cognitive and Brain...

UCLA scientists identify 2,000 important genes Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism. The scientists discovered that some 2,000 genes in a region of the male zebra finch's brain known as "Area X" are significantly linked to singing. More than 1,500 genes in this region, a critical part of the...

Researchers have found that infants, through their daily experience with language, learn and understand the meanings of words for foods and body parts. Upending previous notions of language development in infants, children between the ages of six and nine months were shown to perceive and understand elements of the sounds of their native language. Previously, psychologists believed comprehension of words did not emerge until a child was closer to one year old. Elika Bergelson and Daniel...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
